Gynecological Disorders Practice Questions

Q: Which of the following drugs is commonly used in the treatment of endometriosis?

Combined oral contraceptives. ***Combined oral contraceptives*** - **Combined oral contraceptives (COCs)** are the **most commonly used first-line medical treatment** for endometriosis, as they suppress ovulation and reduce estrogen production, thereby reducing endometrial lesion growth. - They help manage **endometriosis-associated pain** by decreasing menstrual flow and uterine contractions. - COCs are widely prescribed due to their efficacy, safety profile, and additional contraceptive benefits. *Letrozole* - **Letrozole** is an aromatase inhibitor that reduces local estrogen production and has shown efficacy in treating endometriosis, particularly in refractory cases. - However, it is **not commonly used as first-line therapy** due to potential side effects (bone density concerns, teratogenicity) and is typically reserved for cases resistant to conventional hormonal therapy. - It may be used in combination with progestins for better outcomes. *Mifepristone* - **Mifepristone** is an antiprogestin primarily used for medical abortion or in the treatment of Cushing's syndrome. - It works by blocking **progesterone receptors** and is not a standard treatment for endometriosis. *None of the above* - This option is incorrect because **combined oral contraceptives** are the most widely accepted and commonly used treatment for endometriosis.

Q: What condition is diagnosed using the Amsel criteria?

Bacterial vaginosis. ***Bacterial vaginosis*** - The **Amsel criteria** are specifically used for the clinical diagnosis of **bacterial vaginosis (BV)**. - The criteria include the presence of at least three of four findings: **homogeneous discharge**, **vaginal pH >4.5**, **positive whiff test**, and **clue cells** on microscopy. *Antiphospholipid antibody syndrome* - This syndrome is diagnosed based on **clinical criteria** (thrombosis, pregnancy morbidity) and the presence of persistent **antiphospholipid antibodies** (lupus anticoagulant, anti-cardiolipin, anti-β2-glycoprotein I antibodies). - It does not involve the use of the Amsel criteria. *Ovarian ectopic pregnancy* - Diagnosed primarily through **ultrasound imaging** showing a gestational sac or fetal heartbeat within the ovary, often accompanied by clinical symptoms like abdominal pain and vaginal bleeding. - This condition is not related to vaginal infections or the Amsel criteria. *HELLP Syndrome* - **HELLP syndrome** (Hemolysis, Elevated Liver enzymes, Low Platelets) is a severe obstetric complication usually occurring in pregnancy, diagnosed by **laboratory findings** of these specific abnormalities. - It is a systemic condition, not a vaginal infection, and does not use the Amsel criteria for diagnosis.

Q: Which of the following conditions is most commonly associated with malodorous vaginal discharge?

Bacterial vaginosis. ***Bacterial vaginosis*** - This condition is characterized by a "fishy" or **malodorous vaginal discharge**, particularly noticeable after intercourse due to the release of amines. - It results from an imbalance in the vaginal flora, with an overgrowth of anaerobic bacteria and a decrease in protective lactobacilli. *Chlamydia trachomatis* - Often presents with **asymptomatic cervicitis** or mild watery discharge; **malodorous discharge** is not a common or prominent symptom. - While it can cause pelvic pain or dysuria, it's not typically associated with the characteristic smell of bacterial vaginosis. *Trichomonas vaginalis* - Can cause a **frothy, yellow-green discharge** that may be malodorous, but the "fishy" odor is more classically associated with bacterial vaginosis. - Other common symptoms include intense itching, burning, and dyspareunia. *Neisseria gonorrhoeae* - Causes cervicitis, which can lead to a **purulent or mucopurulent vaginal discharge**, but it does not typically produce the distinctive malodor seen in bacterial vaginosis. - Infection can also manifest as dysuria, pelvic pain, or be asymptomatic.

Q: What percentage of ectopic pregnancies occur in the fallopian tube?

90%. ***90%*** - Approximately **90-95%** of all ectopic pregnancies occur within the fallopian tube, making it the most common site. - The **ampulla** is the most frequent tubal site, accounting for about 80% of tubal ectopics, followed by the isthmus and fimbrial end. *75%* - While a significant percentage, **75%** falls short of the actual prevalence of tubal ectopic pregnancies. - This percentage does not accurately reflect the high frequency of implantation within the fallopian tube. *80%* - **80%** is a common statistic for ectopic pregnancies occurring in the **ampulla** specifically, which is a segment of the fallopian tube. - However, the overall percentage for all fallopian tube locations is higher than 80%. *67%* - **67%** is too low and does not represent the vast majority of ectopic pregnancies that are found within the fallopian tube. - Such a low percentage would imply a higher incidence of ectopic pregnancies in other locations (e.g., ovary, cervix, abdomen), which is not the case.

Q: What is the most likely cause of yellow-green watery discharge and pruritus in a female patient?

Trichomonas vaginalis. ***Trichomonas vaginalis (Correct)*** - The characteristic presentation of **yellow-green, frothy, watery vaginal discharge** with associated **pruritus** is highly suggestive of **trichomoniasis**. - Other clinical findings may include **dyspareunia**, **dysuria**, and a **"strawberry cervix"** on speculum examination. - Trichomoniasis is a sexually transmitted infection caused by the protozoan *Trichomonas vaginalis*. *Candida (Incorrect)* - **Candidiasis** (yeast infection) typically presents with **thick, white, cottage cheese-like discharge** and severe pruritus, often described as a burning sensation. - The discharge is usually not watery or yellow-green, and the characteristic fishy odor is absent. - pH is typically normal ( 4.5). *Bacterial vaginosis (Incorrect)* - **Bacterial vaginosis** is characterized by a **thin, gray-white discharge** with a **fishy odor**, especially after intercourse or with alkalinization. - The discharge is not typically yellow-green or frothy. - Pruritus may be present but is usually less prominent than with candidiasis or trichomoniasis. *Chlamydia trachomatis (Incorrect)* - **Chlamydia** infection is often **asymptomatic** in women (up to 70% of cases), but when symptoms occur, they may include **mucopurulent cervical discharge**, intermenstrial bleeding, or lower abdominal pain. - It does not typically cause the **profuse, frothy, yellow-green discharge** with significant pruritus described in this clinical presentation. - Chlamydia primarily causes cervicitis rather than vaginitis.

Q: What is the preferred treatment option for a 21-year-old college girl with mild endometriosis?

Continuous OC pill. ***Continuous OC pill*** - For **mild endometriosis** in a young woman, **continuous oral contraceptive pills (OCP)** are the **first-line medical treatment** according to current evidence-based guidelines (ACOG, ESHRE). - Continuous OCP use provides better suppression of endometriosis by creating a **stable hormonal environment** that prevents cyclic menstrual bleeding and retrograde menstruation, which can worsen endometriosis. - This approach effectively manages symptoms like **dysmenorrhea** and **pelvic pain** while preserving future fertility, and is well-tolerated in young women with the added benefit of menstrual suppression. *Cyclical OC pill* - While cyclical OCPs can help manage endometriosis symptoms, they are **less effective** than continuous OCPs because they allow withdrawal bleeding, which may perpetuate retrograde menstruation and endometrial implant stimulation. - Cyclical OCPs may still provide symptom relief but are considered a **second-line option** when continuous use is not acceptable to the patient. *Progesterone only pill* - **Progesterone-only pills (POP)** can suppress endometriosis by inducing amenorrhea and decidualization of endometrial implants, but they may cause **irregular bleeding patterns**, especially in the first few months. - While effective, they are generally considered when combined OCPs are contraindicated (e.g., migraine with aura, thrombotic risk) rather than as first-line for uncomplicated mild endometriosis. *Danazole* - **Danazol** is an androgenic agent that creates a hypoestrogenic environment, leading to atrophy of endometrial tissue, but it is **rarely used today** due to significant androgenic side effects. - Common side effects include **acne**, **hirsutism**, **weight gain**, and **voice deepening**, which are often unacceptable for a 21-year-old woman, making it an obsolete option for first-line management of mild endometriosis.

Q: Which of the following symptoms is least commonly associated with endometriosis?

Vaginal discharge. ***Vaginal discharge*** - **Vaginal discharge** is a symptom more commonly associated with **infections or cervical issues**, rather than endometriosis. - While women with endometriosis may experience occasional discharge, it is **not a primary or characteristic symptom** of the condition itself. *Infertility* - **Infertility** is a very common issue for women with endometriosis, affecting their ability to conceive due to **inflammation, scarring, and anatomical distortion** of reproductive organs. - Endometrial implants can **disrupt ovarian function**, block fallopian tubes, and create a hostile uterine environment. *Chronic pelvic pain* - **Chronic pelvic pain** is the hallmark symptom of endometriosis, often severe and debilitating. - It results from the **inflammation, adhesions, and nerve sensitization** caused by ectopic endometrial tissue growing outside the uterus. *Dyspareunia* - **Dyspareunia**, or **painful intercourse**, is frequently experienced by women with endometriosis. - This symptom typically occurs when endometrial implants are located on the **uterosacral ligaments, posterior cul-de-sac, or rectovaginal septum**, leading to irritation during deep penetration.

Q: Intrauterine adhesions best seen by?

Hysteroscopy. ***Hysteroscopy*** - **Hysteroscopy** provides direct visualization of the uterine cavity, allowing for precise identification and characterization of **intrauterine adhesions (IUA)** or **Asherman's syndrome**. - It not only diagnoses IUAs but also allows for simultaneous treatment through **adhesiolysis**, making it the gold standard for both diagnosis and management. *Ultrasound* - While ultrasound can sometimes suggest the presence of adhesions through abnormal endometrial appearances or fluid collections, it is generally **not definitive** for diagnosing IUAs. - Its sensitivity is limited, especially for subtle or fine adhesions, and it often requires confirmation by other methods. *Computed Tomography* - **Computed Tomography (CT)** scans are generally **not used** for the diagnosis of intrauterine adhesions. - CT provides limited soft tissue contrast in the endometrial cavity and exposes the patient to **ionizing radiation**, without offering a clear advantage over other imaging modalities. *Magnetic Resonance Imaging* - **Magnetic Resonance Imaging (MRI)** can provide good soft tissue detail and may visualize severe adhesions, but it is **not as sensitive or specific** as hysteroscopy for detecting all types of IUAs. - MRI is more expensive and less accessible than hysteroscopy, and it does not allow for immediate therapeutic intervention.
